IR-5: Incident Monitoring

The organization tracks and documents information system security incidents.

Supplemental

Documenting information system security incidents includes, for example, maintaining records about each incident, the status of the incident, and other pertinent information necessary for forensics, evaluating incident details, trends, and handling. Incident information can be obtained from a variety of sources including, for example, incident reports, incident response teams, audit monitoring, network monitoring, physical access monitoring, and user/administrator reports.

IR-8	The organization: IR-8a.: Develops an incident response plan that: IR-8a.1.: Provides the organization with a roadmap for implementing its incident response capability; IR-8a.2.: Describes the structure and organization of the incident response capability; IR-8a.3.: Provides a high-level approach for how the incident response capability fits into the overall organization; IR-8a.4.: Meets the unique requirements of the organization, which relate to mission, size, structure, and functions; IR-8a.5.: Defines reportable incidents; IR-8a.6.: Provides metrics for measuring the incident response capability within the organization; IR-8a.7.: Defines the resources and management support needed to effectively maintain and mature an incident response capability; and IR-8a.8.: Is reviewed and approved by [Assignment: organization-defined personnel or roles]; IR-8b.: Distributes copies of the incident response plan to [Assignment: organization-defined incident response personnel (identified by name and/or by role) and organizational elements]; IR-8c.: Reviews the incident response plan [Assignment: organization-defined frequency]; IR-8d.: Updates the incident response plan to address system/organizational changes or problems encountered during plan implementation, execution, or testing; IR-8e.: Communicates incident response plan changes to [Assignment: organization-defined incident response personnel (identified by name and/or by role) and organizational elements]; and IR-8f.: Protects the incident response plan from unauthorized disclosure and modification.
PE-6	The organization: PE-6a.: Monitors physical access to the facility where the information system resides to detect and respond to physical security incidents; PE-6b.: Reviews physical access logs [Assignment: organization-defined frequency] and upon occurrence of [Assignment: organization-defined events or potential indications of events]; and PE-6c.: Coordinates results of reviews and investigations with the organizational incident response capability.
SC-5	The information system protects against or limits the effects of the following types of denial of service attacks: [Assignment: organization-defined types of denial of service attacks or references to sources for such information] by employing [Assignment: organization-defined security safeguards].
SC-7	The information system: SC-7a.: Monitors and controls communications at the external boundary of the system and at key internal boundaries within the system; SC-7b.: Implements subnetworks for publicly accessible system components that are [Selection: physically; logically] separated from internal organizational networks; and SC-7c.: Connects to external networks or information systems only through managed interfaces consisting of boundary protection devices arranged in accordance with an organizational security architecture.
SI-3	The organization: SI-3a.: Employs malicious code protection mechanisms at information system entry and exit points to detect and eradicate malicious code; SI-3b.: Updates malicious code protection mechanisms whenever new releases are available in accordance with organizational configuration management policy and procedures; SI-3c.: Configures malicious code protection mechanisms to: SI-3c.1.: Perform periodic scans of the information system [Assignment: organization-defined frequency] and real-time scans of files from external sources at [Selection (one or more); endpoint; network entry/exit points] as the files are downloaded, opened, or executed in accordance with organizational security policy; and SI-3c.2.: [Selection (one or more): block malicious code; quarantine malicious code; send alert to administrator; [Assignment: organization-defined action]] in response to malicious code detection; and SI-3d.: Addresses the receipt of false positives during malicious code detection and eradication and the resulting potential impact on the availability of the information system.
SI-4	The organization: SI-4a.: Monitors the information system to detect: SI-4a.1.: Attacks and indicators of potential attacks in accordance with [Assignment: organization-defined monitoring objectives]; and SI-4a.2.: Unauthorized local, network, and remote connections; SI-4b.: Identifies unauthorized use of the information system through [Assignment: organization-defined techniques and methods]; SI-4c.: Deploys monitoring devices: SI-4c.1.: Strategically within the information system to collect organization-determined essential information; and SI-4c.2.: At ad hoc locations within the system to track specific types of transactions of interest to the organization; SI-4d.: Protects information obtained from intrusion-monitoring tools from unauthorized access, modification, and deletion; SI-4e.: Heightens the level of information system monitoring activity whenever there is an indication of increased risk to organizational operations and assets, individuals, other organizations, or the Nation based on law enforcement information, intelligence information, or other credible sources of information; SI-4f.: Obtains legal opinion with regard to information system monitoring activities in accordance with applicable federal laws, Executive Orders, directives, policies, or regulations; and SI-4g.: Provides [Assignment: organization-defined information system monitoring information] to [Assignment: organization-defined personnel or roles] [Selection (one or more): as needed; [Assignment: organization-defined frequency]].
